Chukwuemeka.

AI-native builder. Full-stack engineer. Founder of DigiKing.

I build AI-integrated software products — from voice AI receptionists to fintech infrastructure — and ship them into real markets. I operate at the intersection of product thinking, engineering execution, and systems design. Based in Nigeria, building for the world. I also run GRACODEV, a free digital skills training program empowering the next generation of developers in Abia State.

01 /What I Build

Selected Work

01Voice AI · SaaS · B2B

DigiKing AI Receptionist Flagship

In Development

A 24/7 AI voice receptionist SaaS targeting hotels, hospitals, and clinics in Nigeria and beyond. Handles inbound calls with human-quality voice, intelligent routing, smart escalation to human staff, and integrations with booking and scheduling systems. Currently in active development with a pitch deck targeting early hospitality clients.

Node.jsReactVoice AI APIsTwilioSupabase
Interesting Problem

Designing escalation logic that knows when a caller's emotional tone or request complexity crosses the threshold where a human must take over — without the caller noticing the handoff seam.

02Fintech · AI · Credit Infrastructure

Cognitive Banking

Competition Build

An AI credit scoring and community micro-bond platform built on OPay's payment rails. Features a TabNet-based scoring engine that reads behavioral financial data, and a multi-agent governance layer for community lending decisions. Built for the OPay National Innovation Challenge 2026.

PythonTabNetMulti-Agent AIOPay APIReact
Interesting Problem

TabNet was chosen over standard gradient boosting specifically for its attention-based interpretability — so a loan officer (or a community) can see which financial behaviors most influenced a credit decision, making the model trustworthy, not just accurate.

03EdTech · SaaS · AI

Clasra

Built

A full AI-enhanced school management platform. Beyond the standard SIS features, Clasra includes an AI canvas system, voice and multimodal agents for teachers and students, and a storyboard-to-video pipeline for generating educational content. Designed as a multi-tenant SaaS for Nigerian schools.

ReactNode.jsSupabaseAI APIsMultimodal Agents
Interesting Problem

Building the storyboard-to-video pipeline required designing a prompt chaining architecture where each scene's visual context carries forward — so the generated video doesn't lose character or setting consistency between slides.

04Fintech · Community Savings

AjoVault

Built

A digital rotating savings platform (Ajo/esusu) with a complete Node.js/Express/MongoDB backend. Handles group creation, contribution cycles, payout scheduling, and payment integration. Built to bring a deeply Nigerian savings tradition onto a reliable, auditable digital infrastructure.

Node.jsExpressMongoDBPaystack
Interesting Problem

The core challenge was modeling the rotating payout queue so it's tamper-proof — once a cycle starts, no admin action can alter who receives next, enforcing the social trust contract the system is built on.

05Logistics · Web App

Delvora

In Development

A logistics and shipment tracking web application with a clean modern frontend and a Supabase backend. Built using TanStack Router and TanStack Query for state and routing, with a Bootstrap/jQuery template integrated for rapid UI scaffolding.

TanStack RouterTanStack QuerySupabaseReact
Interesting Problem

Integrating a Bootstrap/jQuery HTML template into a TanStack Router SPA without rewriting the template required an iframe-based isolation strategy that kept the legacy template's JS scope from polluting the React application state.

06Retail · Fintech · Multi-tenant SaaS

Enterprise POS System

Built

A full multi-tenant point-of-sale platform rebuilt with Clerk for authentication and Supabase for data. Includes Korapay and Moniepoint payment rail integrations, role-based access across tenant organizations, and a clean inventory and sales management layer.

ReactClerkSupabaseKorapayMoniepoint
Interesting Problem

Korapay and Moniepoint have very different webhook timing and verification signatures — abstracting both behind a unified payment event interface meant the rest of the POS logic never needed to know which rail processed the transaction.

About

Prince Chukwuemeka portrait
Prince Chukwuemeka — cetf
Founder · Engineer · Creative

I'm a final-year AI student at FUTO and a self-taught full-stack developer who started building real products before graduation. I work under the DigiKing brand, building AI-integrated SaaS products designed for African markets with global ambitions.

Engineering is my sharpest tool, but not my only one. I think in systems — whether that's a credit scoring model, a biomass energy plant, or a content strategy for thirty days of video. I've shipped products across fintech, edtech, logistics, and voice AI. I've also made things with my hands.

I run GRACODEV, a free digital skills training program in Abia State where I teach full-stack development and digital entrepreneurship to young Nigerians. Giving people tools is part of what I build.

04 /The Wider Picture

Beyond the Screen

01

GRACODEV

A free digital skills training initiative I founded in Abia State. I teach full-stack web development and AI fundamentals to young Nigerians — because access to these skills shouldn't depend on geography or income.

02

Fruitful Waste LLC

A biomass energy venture converting agricultural waste into charcoal briquettes and electricity. I've designed kiln systems, written investor information memorandums, and pitched this to early backers. Engineering isn't only software.

03

Creative Direction

I serve as Creative Director at my church, leading visual and content strategy. I've written thirty-day video script campaigns, designed brand systems, and directed production. Aesthetics and narrative are part of how I think about product too.
